Y., ASSIGNOR TO INTERNATIONAL MOTOR COMPANY, OF NEW, YORK, N. Y., A CORPORATION OF DELAWARE SEAT Application filed April 26, 1926. Serial No` 14,569.

In a copending application of Alfred F. Masury, U. S. Ser. No. 72,928, tiled December 3, 1925, Patent No. 1,637 ,780, there is dis-- closed, as a preferred embodiment, a non-me- 5 tallie yielding cushioning connection or support for a weight qsupporting instrumentality including a block capable of predetermined distortion interposed between say a seat and a base or supporting frame therefor and another block (3o-operating therewith which is capable of lexpansion in direct relation with the distortion of the aforesaid block for the purpose of affording the seat a predetermined character 0f movement. The present invention relates to a' cushioning 'support having the same general characteristics as that disclosed in the aforesaid application and has for is object the control of the compression of the support'in a structure having-certain from the standpoint of manufacture, assembly and use. Accordingly, a bolt is provided, carried with the seat support, toconnect a seat for the first named block on the weight supporting medium and block and the seats for the bolts are so formed as to facilitate their pivotal movement with respect to the belt. In a modification of the invention the seats are so disposed as to permit the nest- 4 3o ing of the blocks in the interest of conservation of space. In the description of the invention, it is to be understood that, whenever any type of supporting instrumentality for a person in either an upright, sitting or reclining position is intended it is referred to,

-for the sake of convenience, as a seat, but such term is to be given the broad interpretation intended. In order that the invention may be clearly understood and readily carried 4.0 into effect the same will now be described more particularly with reference to the accompanying drawings illustrating preferred embodiments thereof, in which:

Figure l is a vertical longitudinal sectional vview showing the application of the cushioning connections according to the present invention, applied to a seat.

Figure 2' is a view looking from above and showing one of the cushioning connections at B0 the rear of the seat shown inigure 1.

Figure `3 is a fragmentary view similar to Figure 1 but showing a modification of one of the rear cushioning connections in which the blocks are nested. N

While the cushioning connection according to the present inventionwill be found particularly applicable in situations where a chair o'r seat is adapted to be supported from the floor of vehicles whereby shocks or vibrations incident to the travel thereof are absorbed or cushioned and prevented from being impressed upon the seat, the followmg description is in nowise to be limited to such use but such cushion support may beused 1n many situations where it is desired to do away with metallic springs in the 4seat cushions in all types of weight supporting media.

In the drawings the form of a unitaryy seat is shown including a back rest secured to a frame b upon which a cushion or the like is supported by say the brackets b. This seat as a whole is adapted to be tilted to a limited extent in a fore and aft direction about a horizontal transverse line lying substantially in the plane of and near the rear edge of a base, in this instance the flanged plate c which is carried on the pedestal d. As in the embodiment shown in the co-pending application the cushioning connection permitting this tilting motion comprises, forwardly of the base one or a plurality of strap hinges e of yielding non-metallic material whereof spaced portions are respectively clamped between opposed flanges b2 on the frame, by means a plate c and the plate c by means say of a vbolt c2. Bearwardly one or a plurality of perforated blocks f capable of a predetermined degree of compression or distortion are located above the plate c between it and a seat g formed by depending flanges g carried with the frame b. Below plate c and between it and a seat h having flanges. It is disposed an eXpansible block i of non-metallic material maintained normally under a predetermined degree of compression so that the block may expand in direct proportion to the compresslon of the block f. In the structure shown in the co-pending a plication the lower seat h is carried rigidly with the frame Z. In

a supporting elementy in i of the bolt b3 and between the present embodiment the seat lz is separate from the frame and is supported by a bolt y' in such manner that as the seat tilts and the blocks are distorted the bolt is capable of relative movement with respect to the seats.

This is effected by forming the outer surfaces of the seats spectively,

Washers or of the bolt.

In the modification illustrated in Figure 3 the base o is recessed as at c3 for the reception of the block e' in nesting relation With the block f. This is conveniently accomplished by disposing` an inverted cup-shaped mem ber 7,: above plate c in register with an aperture c4 therein Within Which the block c is seated and about which the block f is positioned by means of ange 7c forming a rim for the cup. The cup shaped member is secured to the base in any suitablemanner. The block z' may then be retained Within the cup under the desired degree of compression by means of a plate or seat II resting upon the nut jz. In this instance, since the sponge rubber block permits freedom of movement, only the upper seat g need be dished to receive a spherical head ja of bolt 'y'.

By the construction described the assembly of the connection is facilitated and positively maintained by the bolt which also affords means for determining the initial compression to which the connection is subjected.

Modications in the configuration, arrangement and location of the component elements of the seat connection will occur to those skilled in the art and are to be deemed Within the scope of the appended claim.

What I claim is:

In a device ofthe character described, in combination, a seat, a base, a tubular block of yielding non-metallic material disposed between a portion of the seat and the base, said block resting on the base and said seat restingy on the block, cup-shaped abutment means secured to the base, a second similar block ahgned with the first and beneath said abutg and z. concave as at g2, 7a2, reto receive spherically surfaced the like 7" carried With the ends `ment means, flanges on the seat and base to prevent displacement of the blocks, a bolty passing loosely through the seat, the base and both blocks, and having a spherical faced head engaging the seat, and means on the other endy of the bolt whereby the second named block is held against said abutment means and the seat is held to the base.
